Re: J$ Training for Tough Mudder and 3 on 3 Ball
I've done Tough Mudder... Lot's of fun. My advice to you would be to run as much as you can. If you want to breeze through it, get up to 8 miles straight, no stops, under an hour. If you find time to work out at a gym, hop on a treadmill and set the incline to 2, 8 miles, under an hour.
Also, make sure sure to focus on arms, chest, abs and quads. Do you know which Tough Mudder you'll be doing?
